Armed with these instructions, the detective sergeant had undertaken his duties, which had proved more or less tedious up to the time that a fashionably attired woman of striking but unusual appearance had inquired of the hall porter upon which floor Mr. Nicol Brinn resided.

In her manner the detective sergeant had perceived something furtive. There was a hunted look in her eyes, too.

When, at the end of some fifteen or twenty minutes, she failed to reappear, he determined to take the initiative himself. By intruding upon this prolonged conference he hoped to learn something of value. Truth to tell, he was no master of finesse, and had but recently been promoted from an East End district where prompt physical action was of more value than subtlety.

As a result, then, he presently found himself in the presence of the immovable Hoskins; and having caused his name to be announced, he was requested to wait in the lobby for one minute. Exactly one minute had elapsed when he was shown into that long, lofty room, which of late had been the scene of strange happenings.

Nicol Brinn was standing before the fireplace, hands clasped behind him, and a long cigar protruding from the left corner of his mouth. No one else was present, so far as the detective could see, but he glanced rapidly about the room in a way which told the man who was watching that he had expected to find another present. He looked into the unfathomable, light blue eyes of Nicol Brinn, and became conscious of a certain mental confusion.

"Good evening, sir," he said, awkwardly. "I am acting in the case concerning the disappearance of Mr. Paul Harley."

"Yes," replied Brinn.

"I have been instructed to keep an eye on these chambers."

"Yes," repeated the high voice.

"Well, sir"-again he glanced rapidly about-"I don't want to intrude more than necessary, but a lady came in here about half an hour ago."

"Yes," drawled Brinn. "It's possible."

"It's a fact," declared the detective sergeant. "If it isn't troubling you too much, I should like to know that lady's name. Also, I should like a chat with her before she leaves."

"Can't be done," declared Nicol Brinn. "She isn't here."

"Then where is she?"

"I couldn't say. She went some time ago."

Stokes stood squarely before Nicol Brinn-a big, menacing figure; but he could not detect the slightest shadow of expression upon the other's impa.s.sive features. He began to grow angry. He was of that sanguine temperament which in anger acts hastily.

"Look here, sir," he said, and his dark face flushed. "You can't play tricks on me. I've got my duty to do, and I am going to do it. Ask your visitor to step in here, or I shall search the premises."

Nicol Brinn replaced his cigar in the right corner of his mouth: "Detective Sergeant Stokes, I give you my word that the lady to whom you refer is no longer in these chambers."

Stokes glared at him angrily. "But there is no other way out," he bl.u.s.tered.

"I shall not deal with this matter further," declared Brinn, coldly. "I may have vices, but I never was a liar."

"Oh," muttered the detective sergeant, taken aback by the cold incisiveness of the speaker. "Then perhaps you will lead the way, as I should like to take a look around."

Nicol Brinn spread his feet more widely upon the hearthrug. "Detective Sergeant Stokes," he said, "you are not playing the game. Inspector Wess.e.x pa.s.sed his word to me that for twenty-four hours my movements should not be questioned or interfered with. How is it that I find you here?"

Stokes thrust his hands in his pockets and coughed uneasily. "I am not a machine," he replied; "and I do my own job in my own way."

"I doubt if Inspector Wess.e.x would approve of your way."

"That's my business."

"Maybe, but it is no affair of yours to interfere with private affairs of mine, Detective Sergeant. See here, there is no lady in these chambers. Secondly, I have an appointment at nine o'clock, and you are detaining me."

"What's more," answered Stokes, who had now quite lost his temper, "I intend to go on detaining you until I have searched these chambers and searched them thoroughly."

Nicol Brinn glanced at his watch. "If I leave in five minutes, I'll be in good time," he said. "Follow me."

Crossing to the centre section of a ma.s.sive bookcase, he opened it, and it proved to be a door. So cunning was the design that the closest scrutiny must have failed to detect any difference between the dummy books with which it was decorated, and the authentic works which filled the shelves to right and to left of it. Within was a small and cosy study. In contrast with the museum-like room out of which it opened, it was furnished in a severely simple fashion, and one more experienced in the study of complex humanity than Detective Sergeant Stokes must have perceived that here the real Nicol Brinn spent his leisure hours. Above the mantel was a life-sized oil painting of Mrs. Nicolas Brinn; and whereas the great room overlooking Piccadilly was exotic to a degree, the atmosphere of the study was markedly American.

Palpably there was no one there. Nor did the two bedrooms, the kitchen, and the lobby afford any more satisfactory evidence. Nicol Brinn led the way back from the lobby, through the small study, and into the famous room where the Egyptian priestess smiled eternally. He resumed his place upon the hearthrug. "Are you satisfied, Detective Sergeant?"

"I am!" Stokes spoke angrily. "While you kept me talking, she slipped out through that study, and down into the street."

"Ah," murmured Nicol Brinn.

"In fact, the whole business looks very suspicious to me," continued the detective.

"Sorry," drawled Brinn, again consulting his watch. "The five minutes are up. I must be off."

"Not until I have spoken to Scotland Yard, sir."

"You wish to speak to Scotland Yard?"

"I do," said Stokes, grimly.

Nicol Brinn strode to the telephone, which stood upon a small table almost immediately in front of the bookcase. The masked door remained ajar.

"You are quite fixed upon detaining me?"

"Quite," said Stokes, watching him closely.

In one long stride Brinn was through the doorway, telephone in hand! Before Stokes had time to move, the door closed violently, in order, no doubt, to make it shut over the telephone cable which lay under it!

Detective Sergeant Stokes fell back, gazed wildly at the false books for a moment, and then, turning, leaped to the outer door. It was locked!

In the meanwhile, Nicol Brinn, having secured the door which communicated with the study, walked out into the lobby where Hoskins was seated. Hoskins stood up.

"The lady went, Hoskins?"

"She did, sir."

Nicol Brinn withdrew the key from the door of the room in which Detective Sergeant Stokes was confined. Stokes began banging wildly upon the panels from within.

"That row will continue," Nicol Brinn said, coldly; "perhaps he will shout murder from one of the windows. You have only to say you had no key. I am going out now. The light coat, Hoskins."

Hoskins unemotionally handed coat, hat, and cane to his master and, opening the front door, stood aside. The sound of a window being raised became audible from within the locked room.

"Probably," added Nicol Brinn, "you will be arrested."

"Very good, sir," said Hoskins. "Good-night, sir..."

CHAPTER XVII. WHAT HAPPENED TO HARLEY

Some two hours after Paul Harley's examination of Jones, the ex-parlourmaid, a shabby street hawker appeared in the Strand, bearing a tray containing copies of "Old Moore's Almanac." He was an ugly-looking fellow with a split lip, and appeared to have neglected to shave for at least a week. n.o.body appeared to be particularly interested, and during his slow progression from Wellington Street to the Savoy Hotel he smoked cigarettes almost continuously. Trade was far from brisk, and the vendor of prophecies filled in his spare time by opening car doors, for which menial service he collected one three-penny bit and several sixpences.

This commercial optimist was still haunting the courtyard of the hotel at a time when a very handsome limousine pulled up beside the curb and a sprucely attired Hindu stepped out. One who had been in the apartments of Ormuz Khan must have recognized his excellency's private secretary. Turning to the chauffeur, a half-caste of some kind, and ignoring the presence of the prophet who had generously opened the door, "You will return at eight o'clock," he said, speaking perfect and cultured English, "to take his excellency to High Claybury. Make a note, now, as I shall be very busy, reminding me to call at Lower Claybury station for a parcel which will be awaiting me there."

"Yes, sir," replied the chauffeur, and he touched his cap as the Hindu walked into the hotel.

The salesman reclosed the door of the car, and spat reflectively upon the pavement.

Limping wearily, he worked his way along in the direction of Chancery Lane. But, before reaching Chancery Lane, he plunged into a maze of courts with which he was evidently well acquainted. His bookselling enterprise presently terminated, as it had commenced, at The Chancery Agency.

Once more safe in his dressing room, the pedler rapidly transformed himself into Paul Harley, and Paul Harley, laying his watch upon the table before him, lighted his pipe and indulged in half an hour's close thinking.

His again electing to focus his attention upon Ormuz Khan was this time beyond reproach. It was the course which logic dictated. Until he had attempted the task earlier in the day, he could not have supposed it so difficult to trace the country address of a well-known figure like that of the Persian.

This address he had determined to learn, and, having learned it, was also determined to inspect the premises. But for such a stroke of good luck as that which had befallen him at the Savoy, he could scarcely have hoped. His course now lay clearly before him. And presently, laying his pipe aside, he took up a telephone which stood upon the dressing table and rang up a garage with which he had an account.

"h.e.l.lo, is that you, Mason?" he said. "Have the racer to meet me at seven o'clock, half-way along Pall Mall."

Never for a moment did he relax his vigilance. Observing every precaution when he left The Chancery Agency, he spent the intervening time at one of his clubs, from which, having made an early dinner, he set off for Pall Mall at ten minutes to seven. A rakish-looking gray car resembling a giant torpedo was approaching slowly from the direction of Buckingham Palace. The driver pulled up as Paul Harley stepped into the road, and following a brief conversation Harley set out westward, performing a detour before heading south for Lower Claybury, a little town with which he was only slightly acquainted. No evidence of espionage could he detect, but the note of danger spoke intimately to his inner consciousness; so that when, the metropolis left behind, he found himself in the hilly Surrey countryside, more than once he pulled up, sitting silent for a while and listening intently. He failed, always, to detect any sign of pursuit.

The night was tropically brilliant, hot, and still, but saving the distant murmur of the city, and ordinary comings and goings along the country roads, there was nothing to account for a growing anxiety of which he became conscious.

He was in gunshot of Old Claybury church tower, when the sight of a haystack immediately inside a meadow gate suggested a likely hiding place for the racer; and, having run the car under cover, Harley proceeded on foot to the little railway station. He approached a porter who leaned in the doorway. "Could you direct me to the house of his excellency Ormuz Khan?" he inquired.

"Yes, sir," was the reply. "If you follow the uphill road on the other side of the station until you come to the Manor Park-you will see the gates-and then branch off to the right, taking the road facing the gates. Hillside-that's the name of the house-is about a quarter of a mile along."

Dusk was beginning to fall and, although the nature of his proposed operations demanded secrecy, he recognized that every hour was precious. Accordingly he walked immediately back to the spot at which he had left the car and, following the porter's directions, drove over the line at the level crossing immediately beyond the station, and proceeded up a tree-lined road until he found himself skirting the railing of an extensive tract of park land.

Presently heavy gates appeared in view; and then, to the right, another lane in which the growing dusk had painted many shadows. He determined to drive on until he should find a suitable hiding place. And at a spot, as he presently learned, not a hundred yards from Hillside, he discovered an opening in the hedge which divided the road from a tilled field. Into this, without hesitation, he turned the racer, backing in, in order that he might be ready for a flying start in case of emergency. Once more he set out on foot.

He proceeded with caution, walking softly close to the side of the road, and frequently pausing to listen. Advancing in this fashion, he found himself standing ere long before an open gateway, and gazing along a drive which presented a vista of utter blackness. A faint sound reached his ear-the distant drone of a powerful engine. A big car was mounting the slope from Lower Claybury Station.

CHAPTER XVIII. WHAT HAPPENED TO HARLEY-CONTINUED

Not until Harley came within sight of the house, a low, rambling Jacobean building, did he attempt to take cover. He scrambled up a tree and got astride of a wall. A swift survey by his electric torch of the ground on the other side revealed a jungle of weeds in either direction.

He uttered an impatient exclamation. He calculated that the car was now within a hundred yards of the end of the lane. Suddenly came an idea that was born of emergency. Swarming up the tree to where its dense foliage began, he perched upon a stout bough and waited.

Three minutes later came a blaze of light through the gathering darkness, and the car which he had last seen at the Savoy was turned into the drive, and presently glided smoothly past him below.

The interior lights were extinguished, so that he was unable to discern the occupants. The house itself was also unilluminated. And when the car pulled up before the porch, less than ten yards from his observation post, he could not have recognized the persons who descended and entered Hillside.

Indeed, only by the sound of the closing door did he know that they had gone in. But two figures were easily discernible; and he judged them to be those of Ormuz Khan and his secretary. He waited patiently, and ere long the limousine was turned in the little courtyard before the porch and driven out into the lane again. He did not fail to note that, the lane regained, the chauffeur headed, not toward Lower Claybury, but away from it.

He retained his position until the hum of the motor grew dim in the distance, and was about to descend when he detected the sound of a second approaching car! Acutely conscious of danger, he remained where he was. Almost before the hum of the retiring limousine had become inaudible, a second car entered the lane and turned into the drive of Hillside.

Harley peered eagerly downward, half closing his eyes in order that he might not be dazzled by the blaze of the headlight. This was another limousine, its most notable characteristic being that the blinds were drawn in all the windows.

On this occasion, when the chauffeur stepped around and opened the door, only one pa.s.senger alighted. There seemed to be some delay before he was admitted, but Harley found it impossible to detect any details of the scene being enacted in the shadowed porch.

Presently the second car was driven away, pursuing the same direction as the first. Hot upon its departure came the drone of a third. The windows of the third car also exhibited drawn blinds. As it pa.s.sed beneath him he stifled an exclamation of triumph. Vaguely, nebulously, the secret of this dread thing Fire-Tongue, which had uplifted its head in England, appeared before his mind's eye. It was only necessary for him to a.s.sure himself that the latest visitor had been admitted to the house before the next move became possible. Accordingly he changed his position, settling himself more comfortably upon the bough. And now he watched the three cars perform each two journeys to some spot or spots unknown, and, returning, deposit their pa.s.sengers before the porch of Hillside. The limousine used by Ormuz Khan, upon its second appearance had partaken of the same peculiarity as the others: there were blinds drawn inside the windows.

Paul Harley believed that he understood precisely what this signified, and when, after listening intently in the stillness of the night, he failed to detect sounds of any other approach, he descended to the path and stole toward the dark house.

There were French windows upon the ground floor, all of them closely shuttered. Although he recognized that he was taking desperate chances, he inspected each one of them closely.

Pa.s.sing gently from window to window, his quest ultimately earned its reward. Through a crack in one of the shutters a dim light shone out. His heart was beating uncomfortably, although he had himself well in hand; and, crawling into the recess formed by the window, he pressed his ear against a pane and listened intently. At first he could hear nothing, but, his investigation being aided by the stillness of the night, he presently became aware that a voice was speaking within the room-deliberately, musically. The beating of his heart seemed to make his body throb to the very finger tips. He had recognized the voice to be the voice of Ormuz Khan!

Now, his sense of hearing becoming attuned to the m.u.f.fled tones, he began to make out syllables, words, and, finally, sentences. Darkness wrapped him about, so that no one watching could have seen his face. But he himself knew that under the bronze which he never lost he had grown pale. His heartbeats grew suddenly fainter, an eerie chill more intense than any which the note of danger had ever occasioned caused him to draw sharply back.

"My G.o.d!" he whispered. He drew his automatic swiftly from his pocket, and, pressed against the wall beside the window, looked about him as a man looks who finds himself surrounded by enemies. Not a sound disturbed the stillness of the garden except for sibilant rustlings of the leaves, occasioned by a slight breeze.

Paul Harley retreated step by step to the bushes. He held the pistol tightly clenched in his right hand.

He had heard his own death sentence p.r.o.nounced and he knew that it was likely to be executed.
